useInMemoryFileSystem: true and addSourceFilesAtPaths('**/*.*') doesn't work

Describe the bug

Version: 22.0.0

To Reproduce

 // Initialize the project with in-memory file system
  const project = new Project({
    useInMemoryFileSystem: true,
  });

  // Create source files directly in the in-memory file system
  project.createSourceFile('/src/test.ts', 'const a = 12;');

  // List all source files in the project
  const sourceFiles = project.getSourceFiles();
  for (const sourceFile of sourceFiles) {
    console.log(sourceFile.getFilePath());
  }

  // Add source files using a glob pattern
  const addedFiles = project.addSourceFilesAtPaths('**/*.*');
  console.log(
    'files',
    addedFiles.map((file) => file.getFilePath()),
  );

/*
Outputs:
/src/test.ts
files []
*/

/src/test.ts has been added to the project but addSourceFilesAtPaths('**/*.*') cannot find it.

Expected behavior

addSourceFilesAtPaths('**/*.*') should find created file.

You need to save the file to the file system (sourceFile.saveSync() or project.saveSync())
